, Improvements in Levels, of .whic lrthe following is a specification.

This invention relates to levels and has for'an object the provision of a stock com-. posed of a plurality of angularly connected parts to permit the use of the device by carpenters, masons and other artisans to advantage on angular work as well as straight work. 7

A co-ordinate object of the invention is to provide a combined multipart stock and protractor co-operable to lay the angle or determine the plumb of the wall or other body upon which the device is used.

A further object of the invention is to provide a combination level the mainpart of the stock of which may be used in the capacity of the ordinary level and is equipped with sights, spirit levels, etc., which may be used independently of or in conjunction with the auxiliary part 'of the stock, according to the nature of the work involved.

The above and, other objects of the invention will be inpart described and in part understood from the following description of the present preferred embodiment of the invention taken in connection with the accompanying drawings wherein:

Fig. 1 is a side elevational view of a level constructed in accordance with the invention.

Fig. 2 is a top plan view thereof.

Fig. 3 is a bottom plan view of the device.

Fig. 4 is an end elevational view of the peep sight.

Fig. 5 is a similar view of the hair or wire sight.

Fig. 6 is a fragmentary plan view of the bar carried by the main part of the stock showing to advantage the terminal thereof.

The device of this invention consists of a stock generally designated 6 and consisting of a main part or body 7 and an auxiliary part or body 8. The proximate ends of these parts are tapered and equipped with twoway hinges 9 to permit relative lateral movement of the said parts in either direction.

The main stock 7 is equipped, intermediate its ends, with a vertical spirit level 10 of the usual or any desired design. A simi-- lar level 11 is counter-sunk in the top face of the part 7 adjacent the inner end of. the

latter. main part 7 rises upwardly at its outer end, to provide a lift 12 upon which is mounted a hair or wire sight 13. Preferably the sight is detachably mounted by means of a screw or the like. as shown in Figure 2; V r

A bar 14 is detachably mounted upon the upper face of thepart 7 of theilevel and has one end thereof extended with the free terminal thereof reduced to provide an annular terminus 15 which'lies above the pintle of the hinges9. Rising upwardly. from the bar 14 adjacent to terminus 15 is a guide member 16 which slidably receives a peep sight 17. The peep sight maybe held in a desired position in the guide 16 by means of a nut and bolt 18.

Arranged upon the upper face of the auxiliary part 8 of the stock is a base plate 19 which is detachably mounted on said auxiliary part and has two ears-20 extended from the inner .end thereof which are detachably engaged with the base of a protractor 21. The protractor has its upper face suitably graduated with its arc slidably arranged beneath the bar 14. Theinner marginal edge of said bar is bevelled, as

The upper face; or margin of said indicated at 22, to facilitate reading of the to advantage in Figure 8 and is formed to provide an annulus which extends upwardly through'the terminus 15 of the bar 14. The

upper endof the annulus is swelled over the terminus 15 to prevent displacement of the bar 14 and insuring a more facile movement of the parts 7 and 8. I

In order that the parts 7 and 8 may be locked from movement when the desired angularity thereof has been obtained, a set screw 24 is provided which is arranged through the bar 14 and engages the main part 7 of the level. As shown to advantage in Figure 2 the auxiliary body 8 of the stock may be turned at right angles tothe part 7 if desired.

The auxiliary part 8 of the stock is provided with a horizontal spirit level 25 which is preferably arranged midway the ends of said part 8 for use in an obvious capacity.

Preferably the auxiliary part 8 is relatively the protractor is co-opera-ble with the parts of the level in order to lay the desired angle of a wall or the like and that the said parts ma be held in any desired position. The.

sig ts and spirit levels of the device of course functionin a manner Well known in hingedly connected sections, a base plate carried by the auxiliary section adjacent its hinge, a protractor secured to saidbase plate Withits are extended across the hinge point of the sections and slidable across the main section, and a guide plate carried'by said main section and arranged over the protractor are. I

3. A level including hingedly connected level carrying parts one oi which is relatively longer than the other, a base plate mounted upon the shorter part and equipped with lateral extensions, and a protractor detachably secured to said extensions and slidable across said longer stantially as described.
